SPECIFICATION forming part of Letters Patent No. 510,221, dated December5, 1893.

Application tiled May 29, 1893. Serial No. 475,891. (No model.) Y

To all whom it may concern: v Be it known that we, FRANKLIN N. WILD andELMER F. CAMPBELL, of LAnse, in the county of Baraga and State ofMichigan, have invented a new and Improved Sleigh, of which thefollowing is a full, clear, and exact description.

Our invention relates to improvements in lumber sleighs or bob-sleighs,such as are used for drawing heavy loads of lumber, butA theimprovements may be applied to all sizes of sleighs whether heavy orlight; and the object of our invention is to produce a simple,inexpensive and comparatively indestructible sleigh of this kind. Thesesleighs or sleds are usually made of wood and are used up Very rapidly,and another object of our invention is to produce an all metallic sleighwhich is preferably made of steel, which is constructed so as to be verylight and strong, as its parts are made in such a way that they may bevery conveniently assembled and strongly fastened together, and also toproduce a sleigh on which a load may be con- Veniently placed andcarried.

To these ends our invention consists of certain features of constructionand combinations of parts, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings forming a part ofthis speci lication, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a central longitudinal section on the line 1-1 in Fig. 2.Fig. 2 is a plan View of the sleigh; and Fig. 3 is a front end view,partly in section.

The sleigh is provided with suitable runners 10 which are curved in theusual Way soV as to ride easily over obstructions, and to increase theirstrength and to enable them to be made light they are provided withupturned side anges l1, as Vshown best at the right hand in Fig. 3. rlherunners are also turned up at their front ends to form sockets 12 aroundwhich the shoes 13 are turned, as shown at 14, and the sockets also areadapted to receive bolts by which the tongue may be fastened in theusual Way. The shoes 13 are fastened to the runners by means of bolts15, in substantially the usual Way, and a portion of the bolts are alsoused to fasten in place the bearing plates 16 which lie centrally on therunners 10, and these bearing plates the beam 21 to rest firmly upon itand also to provide for the easy attachment of the beam to it. The beam21 is of a generally rectangular shape, and is adapted to lie firmlyupon the bearing blocks 18 to which it is secured. The beam has a bottomplate 212L which rests in end plates 22, these being secured to theblocks 18 and having upturned flanges 23 which embrace the bottom plate2la of the beam and also the base flanges 25 of the side pieces 24 ofthe beam, these side pieces being placed opposite each other and havinghorizontal lianges 25 at top and bottom, as shown best in Fig. 1. Thebeam has also a top plate 26, which lies upon the top flanges of thesidepieces 24, and the top and bottom plates of the beam are firmly rivetedto the langesrof the side pieces by rivets 27. See Fig. 3. The beam isalso provided with long bolts 28 and 28a, near the ends, which projectdownward through it and through the plates 21a into the widened portions20 of the bearing blocks 18, as shown in Fig. 3, and also down throughthe blocks and into the bearing plates 16, as shown in Fig. 1. To theends of the beam 21 are secured knee braces 2lb, these being ofsubstantially the usual shape, but formed of flat metal,and their lowerends are turned to fit snugly against the bearing plates 16 and anges17,V the braces being firmly bolted to the plates, as illustrated inFig. 1.

On the beam is. supported a bolster 29, which is also of a generallyrectangular shape and is made substantially like the beam, the bolstercomprising the bottom and ltop plates 31 and 32 and the side plates 33which have horizontal flanges 34 riveted securely to the top and bottomplates, as shown in Figs. 1 and 3. On the bolster, at its opposite'ends,are

bearing plate, and each block is also widened Vat the top, as shown at2O in Fig. 3, to enable IOO retaining plates 36, which have upturnedends 37, and these are adapted to engage the lumber carried by thebolster and prevent it from sliding on?. Between the bolster and thebeam are preferably arranged wear plates 80 on which the bolster turns,and the bolster and beam are united in substantially the usual way, byaking bolt 35. ln the top of the bolster are slots 32 which permit a hookto be conveniently placed beneath anyobj ect on the bolster when thesaid object is to be moved.

It will be seen from the above description that the sleigh may becheaply made ot metal, steel being preferably used, that the parts maybe easily secured together, and that when once put together the sleighis extremely strong. In practice two sleighs are generally used, thesebeing connected in the way bobsleighs are usually arranged.

Having thus described our invention, We claim as new and desire tosecure by Letters Patentl. -A metallic sleigh, comprising runners havingfiat bottoms and upturned side flanges, shoes secured to the runners,bearing blocks supported on the runners, a cross beam secured to thebearing blocks, knee braces fastened to the beam and to the runners, anda bolster pivoted on the beam, substantially as described.

2. A metallic sleigh, comprising runners having upturned sideflanges,'shoes fastened to the runners, bearing plates secured to therunners and having upturned end flanges, bearing blocks secured to thebearing plates,

a cross beam fastened to the bearing blocks, knee braces secured to thebeam and bearing plates, the ends of the braces abutting with theflanges of the bearing plates, and a bolster pivoted on the cross beam,substantially as described.

3. A metallic sleigh, comprising runners having upturned side flanges,bearing blocks secured to the runners, a cross beam supported on thebearingblock, the beam comprising top and bottom plates and side pieceshaving out-turned fianges bolted to the said top and bottom plates, kneebraces secured to the cross beam and to the runners, and a bolsterconstructed essentially like the crossbeamand pivoted thereto,substantially as described.

l. A metallic sleigh, comprising runners having upturned side flanges,bearing plates secured between the flanges of the runners and providedwith upturned end flanges, bearing blocks supported on the bearingplates, socket plates on the tops of the bearing blocks, a cross beamsecured in the socket plates and bolted to the socket plates and blocks,knee braces fastened to the cross beam and to the bearing plates, theends of the braces abutting with the fianges of the bearing plates, anda bolster pivoted on the cross beam, substantially as described.
